Abstract
The present invention provides the preparation method and display panel of a kind of liquid crystal cell, liquid crystal cell, belongs to liquid crystal display panel technical field.The preparation method of liquid crystal cell of the present invention, including step：The barrier wall structure of the fixed frame at least partly being used for being formed the liquid crystal cell is formed on the first substrate, and injects liquid crystal；The the first pure heat-curable glue for being used for being sealed to the frame of the liquid crystal cell is formed on second substrate；The first substrate and the second substrate operate box, so that the barrier wall structure of the first substrate is accordingly directed at the first pure heat-curable glue of the second substrate；And heat curing operation is carried out to seal the frame of the liquid crystal cell to the described first pure heat-curable glue.The preparation method of the present invention eliminates the frame Mura phenomenons in liquid crystal display panel, and display effect is good near frame.
Description
Technical field
The invention belongs to liquid crystal display panel technical fields, are related to the preparation method of liquid crystal cell more particularly to liquid crystal cell.
Background technology
Liquid crystal display panel is answered more and more widely because the advantage of its protrusion is already known to the mainstream in display panel
For various display fields, including apply in the portable electronic product of various small sizes.
Liquid crystal cell is the basic element of character of liquid crystal display panel comprising TFT（Thin film transistor (TFT)）Substrate, CF（Colorized optical filtering
Piece）Substrate and the liquid crystal layer being formed between TFT substrate and CF substrates.During preparing liquid crystal cell, need by display ruler
It is very little liquid crystal layer to be sealed to form the liquid crystal cell of corresponding size.
Fig. 1 show schematic diagram of existing liquid crystal cell during sealing and curing.In existing liquid crystal cell production technology,
As shown in Figure 1, after TFT substrate 11 is aligned with CF substrates 13, frame uses UV（Ultraviolet radioactive）With heat cure epoxy glue class
The sealant 13 of type is sealed, and specific sealing and curing process is：Sealant 13 is cured using UV first, makes 13 part of sealant
Then solidification carries out heat cure to prevent liquid crystal from being diffused into periphery to sealant 13, sealant 13 is made fully to cure.But
In UV solidification process, as shown in Figure 1, even if being blocked using mask plate 15, UV is inevitably radiated sealant 13
The PI of edge placement（Polyimides）Oriented layer 14, to will produce ion in the frame neighboring area 141 of liquid crystal cell（e-）.Base
In the display panel that the liquid crystal cell is formed, in screen, the ion that the frame neighboring area 141 of liquid crystal cell generates can lead to side
The voltage on frame periphery is different from the voltage of normal region, keeps the liquid crystal deflection near the frame of liquid crystal cell abnormal, therefore, is easy
Display exception occurs for the surrounding of display panel, forms " frame Mura " phenomenon（Such as display brightness it is uneven, cause showing for trace
As）.
Problem above is relatively prominent in small size display panel, especially in narrow frame, small size display panel.
Invention content
It is an object of the present invention to avoid the PI when the sealant of liquid crystal cell carries out UV solidifications to liquid crystal cell from being orientated
The UV radiation effects of the generation of film, to avoid the frame Mura phenomenons in display panel.
To realize that object above or other purposes, the present invention provide following technical scheme.
It is an aspect of this invention to provide that providing a kind of preparation method of liquid crystal cell, including step：
The barrier wall structure of the fixed frame at least partly being used for being formed the liquid crystal cell is formed on the first substrate, and is noted
Enter liquid crystal；
The the first pure heat-curable glue for being used for being sealed to the frame of the liquid crystal cell is formed on second substrate；
The first substrate and the second substrate operate box, so that the barrier wall structure phase of the first substrate
The first pure heat-curable glue of the second substrate should be directed at；And
Heat curing operation is carried out to seal the frame of the liquid crystal cell to the described first pure heat-curable glue.
The preparation method of liquid crystal cell according to an embodiment of the invention, wherein form fixed barricade on the first substrate
In the step of structure, including sub-step：
It is coated with the second pure heat-curable glue in the first substrate；
Heat curing operation is carried out to form the barrier wall structure to the described second pure heat-curable glue.
Optionally, the described first pure pure solidification glue of heat-curable glue/the second be epoxy resin, acrylate or thermal curing agents,
Or it is two or more arbitrary mixture in them.
Preferably, both the described first pure heat-curable glue and the second pure solidification glue use identical material.
According to the preparation method of the liquid crystal cell of further embodiment of this invention, wherein the barrier wall structure passes through resin material
Or acrylic polymer is formed.
In any of the above-described embodiment preparation method, in the heat curing operation, kept under the conditions of 150 DEG C -230 DEG C
20-40 minutes.
In any of the above-described embodiment preparation method, the height of the barrier wall structure is the 1/2 of the thickness of the liquid crystal cell
To 3/4.
In any of the above-described embodiment preparation method, the first substrate is CF substrates/TFT substrate, the second substrate
For TFT substrate/CF substrates.
In any of the above-described embodiment preparation method, in the operation to box, the barrier wall structure is pure by described first
Heat-curable glue coats.
Another aspect according to the invention provides and a kind of preparing the liquid crystal cell to be formed using as above any method.
Further aspect according to the invention provides a kind of display panel comprising liquid crystal cell described above.
The solution have the advantages that in the preparation process of entire liquid crystal cell, UV curings are avoided, especially right
After box operation, it is only necessary to carry out heat cure, therefore, be completely avoided when UV cures to liquid crystal cell in the envelope frame operation of liquid crystal cell
The UV radiation effects of the generation of PI alignment films will not will produce ion in the frame neighboring area of liquid crystal cell, eliminate liquid crystal
Show the frame Mura phenomenons in panel.The display panel that liquid crystal cell prepared by the present invention is formed has the display effect near frame good
The advantages of.
